From 6e5099288c946037476abd1488e4c7ab6b818e2b Mon Sep 17 00:00:00 2001 From: Annaliese McDermond Date: Wed, 3 Apr 2019 21:01:55 -0700 Subject: [PATCH] ASoC: tlv320aic32x4: Add Playback PowerTune Controls commit d3e6e374566e1154820a9a3dc82f7eef646fcf95 upstream. PowerTune controls the power level of the chip. On playback this indirectly controls things like the gain of the various output amplifiers. This can allow for the decrease of output levels from the codec. This adds controls for those power levels to the driver.
